- Release streaming file object for directories in vfatReleaseFCB.
- Removed initialization of caching in vfatAttacheFCBToFileObject. The cache for files is initialized at the first read/write operation. - Merged vfatExtendSpace and VfatSetAllocationSizeInformation in one function. svn path=/trunk/; revision=3339
